Headphones
The MA12000 features High Drive Headphone
Amplication. The output of the High Drive
Headphone Amplication provides plenty of
power with the exibility to utilize a wide range
of headphones types including high impedance
headphones.
Connect your headphones using a stereo ¼ inch
plug to the HEADPHONES jack on the right of the
INPUT Knob. The initial volume of the headphones
will be the last volume used for headphones with a
startup limit of 70. When headphones are connected,
the other outputs will be muted unless this default
setting is changed in Setup.
The MA12000 Headphone Crossfeed Director
Circuitry (HXD
®
) improves the sound
localization for Headphone Listening. HXD
restores the directionality component of
the spatial sound stage normally heard with
Loudspeaker listening. HXD can be enabled or
disabled in Trim functions when headphones are
plugged in. The default is for the HXD circuit to
be on. To change the HXD setting:
• With headphones attached, press and
release the Left Knob (INPUT) to enter
Trim
• Turn Left Knob to the “HEADPHONE
HXD” screen
• Turn the Right Knob (VOLUME) to
choose On or Off

(Trim screen will time-out and exit after
around 10 seconds of no input)

HDMI and Opcal Gain

television sets have sound levels that are lower than

it louder. The ability to adjust the volume boost of
the Optical input has been added so that the Optical
input could be boosted as needed.
